[Gaps in the first layer]

Did you clean the glass with window cleaner product? It does make a big difference.

 

Yes I did it...

Now i have another problem, that in the middle of the print, the machine doesn't extrude more filament. It could be stucked in the noozle...

Could be that i have under-extrusion problems?. It will explain why I have those gaps or sticking problems?.

Hi neotko,

i did use the blue tape because i had a stick problem with heated bed + glue stick, and i was really frustrated:

hope you can see what happened

Hi!!

I use an Ultimaker Original+ and was doing fine until now. For some reason, the printer is not printing everywhere on the surface. But the most extrange of all is that the gaps appear always in the same places...

I´ve leveled the bed a million of times, with no results, slowed down the print speed, changed the printing temperature... nothing seems to work well.

On the attached picture you can see whats going on. I´ve printed PLA 210°C with a bed temperature of 60°C, and a print speed of 40mm/s[media=2885]

Thank you all!
